the PWMIN signal and the internal signals, the
PWMIN signal rate must be calculated by the ex-
ternal microcontroller using the same frequency
signal provided to the chip through the pin fsys.
Digital Multiplier
This unit contains a multiplier executing the multi-
plication of each sample provided by the memory
by the value stored in kval register.
The output value is a 10-bit word, plus the sign bit.
Figure 10.
PWM Converter
The PWM converter receives from the digital mul-
tiplier three 10 bit digital number and converts it
into three PWM signals.
A counter counts up (from 0 to 255) and down
(from 255 to 0) at the Fsys rate in continuos
mode. Three 8-bit input registers are written with
the 8 most significant bit of the word to be con-
verted and compared to the counter value. The
comparator output is:
